METAL HAIR TUBE.

Application led February 23, 1927. Serial No. 170,360.

the permanent waving machines suoli as usey electric heaters. require tubes ot various types t'or steaming the hair.

Some operators use paper tubes saturated with Water or other liquid, others use metal toil rolls, or crude metal tubes with ordinary caps and in most instances, these tubes f are very clumsy, waste much time, and are otherwise inconvenient.

ln the maior-ity ot the processes followed, thc tubes are sealed at the top and bottom with strings or special tools, so that the tube will retain a required amount koit steam, durin the steaming process.

Then too, in many of these cases, the tubes that are used, are only ot a temporary nature, and are destroyed after each operation, thus making the process comparatively expensive.

Having in mind these diticulties, l have evolved and produced what l believe to be an exceptionally novel tube tor the purpose, wherein the construction is such as to insure e'ilvicient performance, one which Willv tullill the requirements of a device ot this class, and one which is believed to be a worthwhile achievement in mechanical etlieiency.

Other advantages and tentures will become aiiparent trom the following description and drawings.

ln the drawings Figure 1 is an elevational viewv ot a hair tube, constructed in accordance with the present invention, showing the manner in which it is used, and constructed in accordance ivith the present invention.

Fig. is a longitudinal section through the saine.

Fig. 3 is a cross section taken approximately upon the plane ot the line 8-3 ot Fig. 1.

Fig. 4 is a perspective View of the inner section of the tube. y

In its preferred form, the invention coinprises a tube constructed ot aluminum or other suitable metal, the saine comprising an inner section 5, and an outer section 6, these sections being telescopically connected together. is' formed With a longitudinal entrance slot On one side, the inner section 5l or opening- 8. Then-at the open end and on one side of this slot, is Jformed WithA a cutout portion or notch 9. Ther outer section `6, on the lother hand, comprises a relatively short sleeve closed at the end 10, and open at the opposite end.

This outer sleeve section is also lformed ivith a longitudinal entrance opening 12 adapted to register with the aforesaid opening 8. In addtion, it is provided at one end With a. notch 18 adapted tocooperate with' the aforesaid notch or cut-away portion 9.

These tivo notches cooperate in forming a hole through which the strands of hair 14: pass. i f

In usingy the device, the hair as is usual, is wrapped around the pin 16. Then the pin with the hair Wrapped thereon is inserted into the improved tube. In order to do this, it is necessary to turn sections 5 and 6 so that the openings 8 and 12 are in registry with each other.

Having done this, the tubes are rotated to close the opening, and to permit certain of the strands et hair to extend out through the cooperating notches 9 and 13 as represented in Fig. 1. Preparatory to Wrapping the hair and inserting the pin and the hair, it is of course saturated With appropriate liquid, and after the steaming process is linishcd, the sections are rotated with respect to each other to open the tube, and to allow the hair and pin to be easily withdrawn.

From the foregoing description and draw ing, it ivill be seen that l have evolved and produced a novel hair tubeL which can be used over and over again, thus providing a time and labor saver and reducing the eX-v pense ot the operator ot a permanent Wav-- ing establishment. The structure is char-` acterized by the advantages already pointed out, and by the additional advantages ot rapidity and smoothness, and rapidity ot manipulation. v Persons familiar With inventions of this -class will undoubtedly be able to obtain a clear understanding of the same and tor this reason a more lengthy description is thought unnecessary.`

`Minor changes in shape, size and re-ar-A rangement of parts may be resorted to Within the scope of the adjoined claims.

Having thus described my invention, what I claim as new is :f-

1. As a .new product of manufacture, a. hair steaming tube otl the class described y einer lne Comprising d pair of telescopicelly Connecting relatively rotatable sections, hei/*ing entrance slots adapted to be brought into regstry, after which the sections may be turned upon each other for closing the openings and completing the steaming process.`

2. As e new product of manufacture, a

hair steaming' tube of the class described` comprising :L pair of coinplementel telescopically connected tubular sections having entrance slots adapted to be brought into registry 'withvezich other for introduction of the huir to be treated and to be turned in directions away from each other to enclose the heir Within seid sections.

3. As a. it new product of manufacture, e

huir steaming tube of the class described comprising en inner tubular section closed ut one end und open at lts opposite end, said section being formed adjacent said opposite 20 end with a notch, end on one side With e longitudinal entrance slot,4 an outer tubular section into Which the inner section telescopes, said lest named section being also provided on one side with en entrance yslot 2 DAVID J.
